Combining JQuery scripts

Combining JQuery scripts

I found a JQuery (1) Tab and (2) Navigation system and they work great but I want them to use the same library. I tried to download the full package, but I cant get the .js files to work when I try to use the full package.

I understand that both require special scripts, but they are both using a jquery library and I would like to use one instance of the .js instead of 2 in my head tags.

Accordion uses
http://www.i-marco.nl/weblog/jquery-accordion-menu/
   jquery-1.2.1.min.js
   menu-collapsed.js
   style-accord.css


Tabs uses:

jquery-1.js
ui.js
ui_002.js
